As an important tool for offshore operations, offshore containers must undergo strict testing and maintenance to ensure their safety and reliability. NDT is an important method for offshore container inspection，which can effectively detect defects, cracks and fatigue on the surface of containers, and ensuring the reliability and safety of the container.
Some common methods of NDT for offshore containers are: ultrasonic testing (UT), magnetic particle testing (MPT), eddy current testing (ECT), X-ray testing.
TLS usually adopts the method of MPT. This detection is based on the adsorption characteristics of magnetic powder under the action of a magnetic field. By coating a layer of magnetic powder on the surface of the container and detecting the distribution of the magnetic powder under the action of a magnetic field, it reveals cracks and defects. The specific detection process is as follows:
